Public bug reported: (sorry for my English)
Problem: On my laptop (Lenovo 3000 N200, Ubuntu 11.04, PAE kernel: linux-image-2.6.38-8-generic-pae) not working resume after suspend to RAM. Suspend work fine. Resume after suspend not working. The system appears to come back but is unresponsive: display is turned off, the system can't be pinged or accessed through the network, and keyboard key "CapsLock" not light LED (kernel is hung-up?). When I booting to usual kernel (linux-image-2.6.38-8-generic) resume after suspend to RAM working fine. And on Ubuntu 10.10 (Maverick) resume after suspend working fine with PAE kernel. I made this steps: https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume My battery is good. And I using AC power. I not using encruption for "swap" or "home" partition. Just for ~/Private directory via tool ecryptfs. Did the machine break while going to sleep or waking up? Machine break while waking up. Is it reproducible? Yes. It is repeated every time. Did it work before? Yes. It is work before, all time in Ubuntu 10.10 (Maverick) Do you end up with flashing Caps Lock light or similar? No. Caps Lock light not flashing. I trying suspending from text mode with this steps: - add to kernel parameters no_console_suspend; - shut down X-server (servcie gdm stop); - Set font: (setfont /usr/share/consolefonts/Uni1-VGA8.psf.gz); - Making suspend (sudo pm-suspend); And restore not work with the same problem. No additional messages and other information was displayed. I made this steps: https://wiki.ubuntu.com/DebuggingKernelSuspend ""resume-trace" debugging procedure for finding buggy drivers" not helping for me. on dmesg displayed only "Magic number *" but not "hash matches" lines. After repeatable attempts, one time I found line: [ 0.853200] Magic number: 11:870:490 [ 0.853249] acpi PNP0F13:00: hash matches But i can't find module for this device (i8042) in lsmod. May be it is statically compiled in kernel. And this message not displayed any time after... $ dmesg | grep -i PNP0F13 [ 0.300332] pnp 00:09: Plug and Play ACPI device, IDs PNP0f13 (active) [ 0.821151] i8042: PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12 I tried to boot into single mode. And make steps for debugging from text mode and resume-trace, but it is not help. I tried to boot with kernel parameter "init=/bin/bash" and make steps for debugging from text mode and resume-trace, but it is not help. I tried to boot with kernel parameter "init=/bin/bash" and unloading _all_ as possible modules that showing by lsmod (lsmod | cut -f1 -d" " | grep -v Module | while read EACH; do modprobe -vr $EACH; done) and make steps for debugging from text mode and resume-trace, but it is not help. And hibernate not working too for me. Only work solution for me - is it not using PAE kernel...
